Netgear 8000 in a reboot loop #136

Closed lvincent81 closed 1 year ago

Trying to unbrick a R8000 that is in a reboot loop.

It's so close to working. I just get the timeout after a few seconds at the uploading step

I've tried a few official firmware versions, this is the smallest. No luck so far.

I ended up restoring the firmware via TTL USB and tftpd, so weird this didn't go. I later found out that the owner had put the init file for freshtomato on, but it must of been a version for a different router. The router would load the image, and I could even dump into the serial console when connected via serial it was just something in the boot process that was failing and causing the continuous restart.
